Option three - enter Llorente

The Blues prefer a loan, Spurs are keen on a permanent deal - but Batshuayi rejects the move anyway because he wants to be a first-choice striker, not go from being behind Alvaro Morata at Stamford Bridge to being back-up for Harry Kane at Tottenham. So...

Option four... back to option two

Let's back this up and return to Aubameyang going to Arsenal, Batshuayi joining Dortmund and Giroud moving to Chelsea to complete the equation.

But will Arsenal reach an agreement with the Blues?

If not, will Chelsea find an alternative to replace Batshuayi?

If not, and Batshuayi stays, will Dortmund find another striker to replace Aubameyang? The Bundesliga side have previously said he will not be allowed to leave without an alternative in place.
